2. Description of the Prior Art

Human has been being suffered threatening of mosquitoes since the latterexisted in the world; when a mosquito bites, the skin of the man bittenirritates, not only this, he feels awful itching, and mosquitoes are themedia of propagation of various diseases such as Dengue fever, malariaand Japanese encephalitis. Therefore, it is really important to be surehow to avoid mosquito bites.

However, in the most conventional mosquito repelling/killing measuressuch as mosquito-repellent incense, insecticide or mosquito-repellentliquid, mosquito-repellent incense is the one used by flaming of theincense to emit gas for killing mosquitoes, so that mosquitoes cannotget close to it; however, such mode of mosquito killing generates densesmoke and irritating smell which contaminates air and discomfortspeople, and flaming of the incense is subjected to fire disaster, thismeans it has latent high danger and thus is not desired.

Killing mosquitoes by using insecticide does not need burning, but it isstill seriously harmful to human bodies after long-period using byvirtue that the chemical medicine therein has residues not so easy to bedecomposed, and this can result a problem against environmentalprotection; besides, using insecticide can also generate irritatingsmell and thus is not desired too.

Another way for mosquito repelling is spraying of mosquito-repellentliquid, the liquid is sprayed onto the skin of a person to give odorwhich mosquitoes are afraid of and do not dare to bite. However, suchway is subjected to irritate skin and is unsuitable for long timeprotection especially for the whole body of a person, and it rendersskin sticky. In these views, spraying of mosquito-repellent liquid isneither the best way of mosquito repelling.

In order to improve the mosquito-repellent incense, insecticide andmosquito-repellent liquid, electrically used mosquito-repellent incenseand mosquito-repellent devices were provided. Electrically usedmosquito-repellent incense has an electric heater to heat amosquito-repellent slice of incense to emit gas which mosquitoes areafraid of. While a mosquito-repellent device applies the nature ofmosquitoes, by the fact that biting mosquitoes all are those femalemosquitoes in spawning, they do all they can to evade male mosquitoes bynature; thereby, the mosquito-repellent device emits sound wavessimulating the sounds of male mosquitoes to get rid of femalemosquitoes. The aforesaid two ways can both achieve the effect ofmosquito repelling, they are mostly stationary and each is singly placedat a location, they can not completely meet the situations of theenvironment outside, and may be inefficient in mosquito repelling or maybecome nullified and do not meet requirement of people.

In view of this, the inventor of the present invention provided thepresent mosquito repelling/killing device to avoid the defects of theconventional measures; the repelling/killing device can surely be usedirrespective of the environmental influence outside.
